Until it hurts them politically, nothing. The only way it hurts them politically is if their allies in the media turn on them. The dems will do and say anything as long as the press supports them. BECAUSE it is the press that is feeding them the pole numbers, which the same media use as a measure of how successful they are influencing public opinion. Polls today are the scoreboard the media uses to see how they are doing pushing their agenda. They hammer the public with bias and BS and fake news, then check to see if they have moved the polls with their reporting.
If its dismissed with prejudice, Democrats would have to find new grounds for impeachment.
That would take time and I don’t think they have in them to build a bipartisan case for one.
They’re lazy and think all their political problems would be solved by waving a magic wand.
Then again, Democrats are like the Bourbons: they forget everything and they learn nothing.
