Washington (CNN) As the Senate prepares to vote this week on Neil Gorsuch's nomination, it's unclear yet whether Republicans will have enough votes to end an expected Democratic filibuster. Republicans, who have a 52-48 majority, need a total of eight Democrats to get to 60 -- the critical number required to end the filibuster. If they don't reach 60, they can still get around that filibuster, but it would require taking a highly controversial step to change the Senate rules, a move also known as the nuclear option. RELATED: Here's where Republicans stand on the nuclear option Republicans already have three Democrats who will vote with them to end the filibuster, so they need five more of the remaining eight undecided Democrats -- as of Sunday -- to do the same and reach that 60 number.Republicans need at least give more Democrats to help them confirm Neil Gorsuch under current rulesThe GOP has three Dems, but they've only got nine undecideds left to choose from as of Sunday 
 Question:Here's a look at the nine undecided _ and what they've said recently about Gorsuch:.

(CNN) This is the story of a little PO box in Northern Virginia and the conspiracy that wasn't. When the Republican presidential primary was still in full swing in March, officials from Donald Trump's campaign promoted a conspiracy theory -- one of many -- insisting there was a nefarious link between his political opponents and an anti-Trump super PAC. It began this spring when a group called Make America Awesome, an anti-Trump group, posted a photo of Trump's wife, Melania, that criticized her for posing semi-nude in a magazine photo shoot. Trump responded by crudely lambasting the physical appearance of Ted Cruz's wife, Heidi, and he justified it by claiming that Cruz was behind the attack on his own wife.Why do many campaigns and Super PACs share the same PO box?The reason is a lot less interesting than the conspiracy that has been alleged 
 Question:Because those groups listed the same address, they claimed it was proof that the anti-_ forces were operating from the same source.
Donald Trump
