1) If what they did with voting for impeachment were legitimate, it wouldn't have been a vote along party lines; it never has been before. If Trump were guilty, many Republicans would've voted with Democrats in concern for what their constituents would say if they didn't.
2) We know exactly what Trump said during his phone call because he immediately shared the transcript but for some strange reason, Democrats tried to make it appear it was a danger to our national security. It's so absurd that it's almost laughable if it weren't so serious.
3) If Trump did do what Democrats said and gave Ukraine an ultimatum that they wouldn't receive foreign aid unless they began an investigation into the Biden's, then why in the world didn't they do it? If it were true what Democrats were saying, Ukraine would've began the investigation as soon as the ultimatum left Trump's lips. In a court of law, jurists would've looked at this point alone and given a non-guilty verdict.
4) Some Democrats have spoken about impeaching Trump from the moment he took office. Instead of spending their time working on the needs of U.S. citizens, they've spent three years trying to come up with something to take him out and somehow send a message that Hillary should've won. They've been so enraged with Trump from the beginning that they threw out common sense and logic and rendered themselves completely useless to their constituents. This is disgustingly sad.
I could go on and on of course, but I'll stop at the above. No telling how long the Senate hearing will last while the state of our union goes on without assistance. The Senate will not vote for impeachment so all this time will have been a waste. By the way, let's say Trump did get impeached for some reason, it doesn't prevent him from running again in 2020 and according to the polls, he'd probably win again because people are so disgusted with politicians. Representatives in the House and Senate have deplorable ratings compared to President Trump, they don't act like it, they act like they're morally superior, but they aren't. They are corrupt, they just don't understand that we all realize it.
