Input: Consider Input: Trump took to Twitter on Tuesday to claim that Tennessee Republican helped "give us" the nuclear deal with Iran negotiated by President Barack Obama's administration. Earlier this month  he claimed that  Corker  is "largely responsible for the horrendous Iran Deal!"
 Corker  the chairman of the Senate Foreign Relations Committee   was in fact a vehement critic of the deal that emerged from international negotiations in the summer of 2015. After the deal was unveiled   he  wrote in an op-ed for The Washington Post that "Congress should reject this deal and send it back to the President."
 Corker  plotted efforts to block the deal  banding with Republicans -- and even some Democrats -- in an attempt to block the deal.
The following month   Corker  did just that  joining with the bipartisan group to vote against the deal. A procedural vote to move forward a resolution to reject the nuclear deal fell shy of the required 60-vote threshold.
Even before that vote   Corker  helped push through the legislation that would ultimately grant Congress powers to review the deal  which the Obama administration contemplated approving without congressional oversight.
 Corker  said such an attempt would be "a direct affront to the American people and seeks to undermine Congress' appropriate role" in a March 2015 letter to Obama.
 Corker 's calls for congressional review of the nuclear deal that was still being negotiated in the spring of 2015 ultimately led to the Iran Nuclear Agreement Review Act  which Obama ultimately signed despite initially opposing the measure.
That could be what White House press secretary Sarah Sanders was referring to on October 10 when she claimed: " Sen. Corker  worked with Nancy Pelosi and the Obama administration to pave the way for that legislation and basically rolled out the red carpet for the Iran deal  and those are pretty factual."
 Corker  defended the bill against that criticism in September 2015  noting that the legislation "actually took power back from the president."
"Without it  he could have unilaterally implemented the deal immediately. The President never would have been forced to submit the agreement to Congress and there would have been no review and no debate on this critical national security issue "  Corker  said then.
Trump's criticism of  Corker  on the Iran deal is also curious given that Trump initially considered  Corker  as a candidate for vice president and later secretary of state  in large part due to his foreign policy chops.

Input: Consider Input: My name is Graham Weinschenk and I am a Democrat. Among other things  I believe in a womanâs right to choose  that diversity strengthens us  that love will always win  and that protecting the environment is a necessity. These are not things that  âDemocraticâ Congressional candidate Sergio Coppola (6th CD)  believes in.
There are a number of problems with the âIssuesâ page of Cappolaâs website. First   he  fails to actually take a position on most of the issues listed.  He  walks a fine line of attempting to take both sides of most issues. In the process of doing this   he  reveals some pretty outrageous things  which are enumerated below:
 Coppola  Does Not Support Common Sense Gun Control
 Coppola âs position here is incredibly unclear.  He  argues that guns are essential for âthe ability to form a militiaâ and that âaccess to guns is a constitutional right for self-protectionâ. However   he  does support regulations that would prevent the mentally ill from buying guns. But that seems to be where  he  draws the line.  Coppola  then makes a non-specific statement that gun holders need to face more accountability. What does that mean?
 Coppola  is Both Pro-Life and Pro-Choice?
This one is one of the strangest because  Coppola  seems to make both arguments here.  He  says that  he  âbelieves all life is importantâ and that  he  â[does] not support abortion as a method of birth controlâ. Then  he  does an immediate 360 and says that  he  believes âthat a woman has a right to decide what should happen to her bodyâ. Which is it?
 Coppola  Doesnât Understand Being LGBT
Although  Coppola  does say that  he  is against limiting access to government programs and benefits based on sexual orientation   he  also says that a personâs sexual orientation is a DECISION. Itâs 2017. Really.
 Coppola  Believes that America Was Created Based on Christian Principles
Again  there are some positives and negatives here.  He  believes that our laws should be further separated from religion  yet  he  also believes that America was founded based on âChristian principlesâ. This is just factually incorrect. The principal behind both of these are very different.
 Coppola  Is All Over the Place on Immigration
This one just really doesnât make sense. First   he  says that immigration is key to American culture. Then   he  says that immigrants must âassimilateâ to American culture.
 Coppola  Wants a Flat Tax
Again   Coppola  got this right out of The Heritage Foundation. Having a flat tax is extremely regressive  and would do absolutely nothing for the struggling working class.  He  claims that  he  wants a flat tax of 23%  and  he  says that this would lead to everyone paying their âfair share.â Really? 23% for someone making $30 000 a year is a lot different than someone making $300 000 a year  or $3 000 000 a year.
 Coppola  Is an Isolationist
 Coppola  apparently has an issue with the amount of money that the United States spends overseas on goodwill projects and development (a tiny percentage of the budget  by the way  with most of the money coming back to the U.S. in military sales  purchases of American goods and services  etc.). In other words   Coppola  would rather see the US isolate itself than operate as the leader of the free world. We canât afford to take a step back from our spot on the world stage. I must add that  Coppola  also supports cutting military spending.
