(Axios) With a near party-line vote on impeachment rules expected in the House Thursday morning Democrats are confident while Republicans are focusing on swing states to shore up support. Why it matters: Democrats say the vote will accelerate the inquiry and will give them more tools to conduct their investigation. The mid-morning vote is scheduled in the middle of testimony by Tim Morrison a National Security Council official who has decided to leave the administration to pursue other opportunities. Democrats are going for a jackpot by asking former Trump national security adviser John Bolton to appear behind closed doors next week. A source close to Bolton tells Axios Margaret Talev that Bolton wont testify unless compelled via subpoena.But if Bolton is compelled look out: He knows a lot and wont be demure or hold back. The Trump re-election campaign is looking at impeachment largely through the lens of the swing states the president needs to win in 2020.
