There is a corresponding lose-lose situation for the Dems. If they abort the impeachment they will kill their GOTV for 2020 and probably lose their House majority as well as getting stomped in presidential race. If they go to a long and detailed Senate trial Cocaine Mitch and Graham will see to it that all the Democratic dirty laundry in Ukraine, China and Spygate gets fully exposed to the public, including the low information public. That would be worse for them, imo.
I agree that the Senate trial is far riskier for democrats, but I don’t think they have been prone to choose the risk averse box of their strategy charts lately, mostly due to TDS in their party. Even though it could get really ugly for them if the Senate investigations are successfully able to pull a lot of the democrat corruption under the Ukraine/impeachment umbrella, to them pulling up short on actually impeaching Trump in the house would be too hard for their pride to swallow.
Even still, I am beginning to think more and more that they will have to avoid having this thing go to the Senate. If they do, Nancy and Adam can having a huge press conference and mix two message; 1) slam and slander Trump as evil with a thousand pointless accusations, and 2) say that for the benefit of unifying the country they are going to stop short of a full impeachment and sending it to the Senate to prolong all the strife, and even though they ‘proved’ high crimes and misdemeanors, they are going to be the part of healing. heh
