That is false, as already explained.
Actually, some polls indicate that more independents are in favor of impeachment than against it, whereas others indicate that there are more independent voters against impeachment than for it. In both cases, a signficant number remain undecided. Polls clearly show that numbers are not fixed. Source:

Recent polls seem to show opposition to impeachment is slightly stronger than support for it among independents. For example:

Besides, the Republicans fear Trump's base because they have to get through a GOP primary. And primaries tend to have low overall turnouts but high fanatic turnout.
True, and another reason why it's extremely difficult that Republican senators will change their minds. Again,
a lot more evidence against Trump would be needed (not just evidence that he asked for an investigation on Biden in exchange for aid, but rather, things like planting evidence and the like).
Of course, if a senator will lose anyway if he votes against, he might just vote for it if he agrees (or just hates Trump), but far more evidence would be required, at least for nearly all Republican senators. A few are probably already convinced to vote against him, but very few.
