Trump just admitted he is actively trying to meddle in the election, by shutting down the US Post Office.

 He is refusing any deal that gives the USPS badly needed funding, and along with it funding for MUCH badly needed aid, cuz he thinks it wold hurt his chances for re-election.

1) Democrats want funding in a coronavirus relief bill for the Postal Service.

2) They want that money so that the USPS can adequately deal with what is expected to be a major surge in mail-in and absentee balloting due to concerns about in-person voting spreading Covid-19.

3) Trump refuses to give them that money -- or include it in any sort of deal -- because, without it, there won't be the ability for the people to cast more mail-in ballots, or -- and this is really important -- for election officials to effectively count them all.
