The big picture: Here’s a visual look at just how strong that wall is: 51 Republican senators from states Trump won in 2016. He only needs 34 to save him from being convicted and removed from office if the House impeaches him.

So if Mitt Romney or Ben Sasse feel like voting to convict, they can and it wouldn’t make a difference.

The red wall doesn’t include Susan Collins or Cory Gardner, the two Republican senators from states that voted for Hillary Clinton (Maine and Colorado). Both are up for re-election next year.

They could vote to convict too, and it still wouldn’t matter.

Remember that impeachment, which only takes a majority vote in the House, doesn’t end Trump’s presidency. That only happens if two thirds of the Senate votes to convict and remove him — 67 senators if they all show up.
