Input: Consider Input: Sen. John McCain (R-Ariz.) . (Cliff Owen/Associated Press)
What happened to  you ?
But boo Sen. John McCain (R-Ariz.) you did  at the behest of President Trump during a rally in Alabama last week.
Mike Allen of Axios further reported this week that Trump has been “physically mocking” the thumbs-down gesture  McCain  used to deliver the deciding vote against the Republican health-care bill in July. Did that mocking involve an imitation of  McCain ’s stiff arm movements? In case you haven’t read a newspaper in the 45 years since we played on the same Dixie Youth Baseball team together   McCain  got the hell beaten out of  him  by the communists who held  him  in the Hanoi Hilton for more than five years.
Meanwhile   McCain  continued receiving the beatings that would forever leave  him  incapable of lifting  his  arms over  his  head.  He  kept enduring torture because  he  refused to leave  his  band of brothers behind.
Do you have that kind of character? If you booed  McCain  at last week’s rally  don’t bother answering. Someone has obviously failed you in your life; you probably need to spend some time figuring out who that was. And if you still go to church  you may also want to pray for all those around you who put tribal politics ahead of basic humanity.
Then maybe you should drive home and tell your children the story of John McCain’s sacrifice. If you can teach your children that lesson of heroism  there’s a chance they might grow up to have more character than the president you now praise.

Input: Consider Input: Mariah Carey  undeterred by last yearâs performance  will take to the stage once again in Times Square to ring in the new year on live TV.
The star  along with Dick Clark Productions  issued a joint statement on Friday announcing  Carey  as the headliner for âDick Clarkâs New Yearâs Rockinâ Eve with Ryan Seacrestâ broadcast.
Careyâs manager blamed the production and technical difficulties that producers knowingly failed to fix. Dick Clark Productions called the accusations âoutrageous and frankly absurd.â  Carey  eventually broke her silence on the troubled performance  saying she was âmortifiedâ and that she intended to take a break from social media.
Now it seems as though everyone is ready to put the messy past behind them.  Carey  will join the likes of Britney Spears  Nick Jonas  Kelly Clarkson and Shawn Mendes as the world rings in 2018.
 Careyâs  forthcoming New Yearâs Eve performance will top an already merry holiday season for the star. In addition to performing her annual Christmas tour   Careyâs  famous single âAll I Want For Christmas Is Youâ has been played more than 100 million times this month alone  according to Forbes.

Input: Consider Input: The Senate is expected to vote Saturday on whether to take up the legislation. The majority leader  Harry Reid  D-Nev.  refused to say Thursday whether he had the 60 votes needed to clear that procedural hurdle.
 While the guts of the Senate and House bills are similar  Reid devised a new method of financing coverage  not found in any other major health bill. His proposal would significantly increase the Medicare payroll tax for high-income people.
 Supporters of abortion rights were pleased with the treatment of abortion in Reid's bill. "It maintains the decades-long compromise of no federal funds for abortion  while allowing a woman to use her own private funds for her reproductive health care " said Sen. Barbara Boxer  D-Calif.
 Reid and other Democratic leaders said that the unveiling of the bill  composed in his office  had given them political momentum going into the first test vote. Despite solid Republican opposition  the Democrats said they were confident they could enact some kind of national health insurance program  a goal that has eluded politicians for more than 75 years. But Congress appears highly unlikely to meet President Barack Obama's goal of finishing work on the bill this year.

But Congress appears highly unlikely to meet President Barack Obama's goal of finishing work on the bill this year.
 The Congressional Budget Office estimates that Reid's bill would provide coverage to 31 million people who are uninsured  while the House bill would cover 36 million people.
 Many provisions of the House bill would take effect in 2013. But to help hold down the cost of the bill  Reid decided to delay the effective date for many provisions by one year  to 2014.
 Reid's bill would impose a tax on "Cadillac health plans" -- employer-sponsored group health plans with premiums more than $8 500 for individual and $23 000 for family coverage. He would impose a new 5 percent tax on "elective cosmetic medical procedures." And he would impose annual fees on insurance companies and makers of medical devices and brand-name drugs. By contrast  the House relies on an income surtax to raise $460 billion from 2011 to 2019. The tax would be 5.4 percent of adjusted gross income exceeding $500 000 for individuals.
