Identity Politics is politics based on assigned and assumed collective group identities rather than based on individuals. It is a form of prejudice.
So if you tell people you are a Democrat who supports the Green Party Platform, you are expressing prejudice?
No, that would be an attempt to identify your politics through group identity rather than politics based on assigned or assumed group identity. Identity politics would be more along the lines of Republicans voting for Trump and backing all he says no matter what it is or opposing everything Obama because he is the other (be it black or be it Democrat). It would also be identity politics to demand that everybody who voted for Trump must be a racist. It would also be identity politics to say "there is a special place in hell for women who don't vote for Hilly Clinton" or to consider black people who vote Republican to be traitors to the race, or white people who date black people to be race traitors, etc. It would also be identity politics exclude black people or women from opportunities afforded white people or men regardless of merit, and also be identity politics to provide scholarships to black people or women regardless of individual circumstance or academic merit.
I think that the needed distinction is between when one merely recognizes objective features of people that are define different categories (all the examples given by others to refute your point) versus viewing or treating people and situations based upon these broad categories rather than individual traits that are actually relevant to the judgment or decision being made.
Most of your examples are of the latter, except for the two I bolded. Voting for Trump is an individual chosen action that most certainly does reflect one's moral character and ideology. It is in fact an objectively sound predictor of racism. Odds are very high that most of the 25% of adult Americans who voted for Trump are more racist than whites that did not vote for Trump.
To infer that every single one of them is a racist may require an unreasonable leap rooted in "identity politics", however one can get pretty close without doing so. Trumps rhetoric was so grossly racist and his base support so obviously coming from xenophobic white supremacists that no one but a racist could think he is anything but vile scum and not strongly fear the increased racism his presidency would and is encouraging. That leaves the only plausible non-racists who would vote for him being people who hate him and fear his racist impact but hold their nose and vote for him either out of their own identity politics or because they sincerely think his presidency would help them in ways that outweigh the racism he will engender. Note that the latter motive still means one has a morally questionable selfish disregard for the harm of racism, and the former is just a form of group think not much better than racism.
As to the second example of black "traitors" that kind of depends what is entailed by "traitor". If a Trump presidency is bad for the vast majority of blacks (and it objectively is), then it is just and objective fact that a black person voting for Trump is harming most people of their own race, which is likely to mean harming many of the people they know and are presumed to care about. Is it worse to harm one's own race than another race? No, that assumption would be "identity politics". However, it is arguably worse to harm the black community regardless of whether they are your own race, given the amount of harm the US government has already inflicted upon them. So, at minimum, this example is less clear cut as an instance of identity politics.
