1) withholding funds for policial purpose is abuse of power. Or, asking another country to announce fake investigation of polical opponent also is abuse of power. Together its bribery.
Asking is not bribing. Bribing is when you have negative information about somebody, and threaten to expose them if they don't do your bidding. No evidence Trump ever did that.
2) "If you don't announce that it's a bank robbery, it's not a bank robbery!"
Terrible comparison. A better one would be taking money out of the bank. If you withdraw cash from your savings account, and your neighbor sees you have a lot of cash, which you tell him you got from the bank, and he assumes you robbed the bank, that's not grounds to arrest anybody if he calls the cops.
Trump openly stated he had several good reasons for the withholding of money, including one of his campaign promises which was pressure the rest of the UN members to pony up a bit. The Democrats, the liars they are, ASSUMED it had to do with Slow Joe's candidacy, and they probably didn't even do that. Since they are looking for ways to try and get rid of Trump, they are using that as a cheap excuse. Like I said, you can't impeach somebody based on mind reading, because nobody can read minds on this planet.
3) can you read?
it says Ukraine investigated the Bidens
The better question is can you read? Instead of just Googling links, try opening up the story for yourself.
4) Trump benefits from one of the leading opposing candidates under "investigation"
And that's not an impeachable offense either.
