They're not voting because they don't need to.
However, I'm fascinated by your immediate uptake of the republican talking points, which seem to have absolutely nothing to do with whether or not Trump actually did attempt to get a foreign government to investigate a political rival - an allegation that has been following Trump around since before he took office. I absolutely love that your main point here is that somehow Pelosi didn't follow procedure (looks like she did), and not at all that your guy may have attempted to bribe foreign governments into helping him win the next election, and then effectively said he'd like to execute the whistleblower that point out this impropriety (obstruction), refuses to comply (obstruction), accused Pelosi of treason (obstruction), and already was obstructing in the previous Russia investigation.
But no, let's ignore all that stuff, let's ignore the US President joking about killing people that would inform the public about his misdeeds and focus on a congressional procedural point. That seems prudent.
