Tell her the finger pointing is at least somewhat by design, because by blaming the other guy the two party system remains in power. I don't know, might save that for another day........Anyway, I'll answer your question in liberal Vs conservative fashion, because it's more consistent then trying to figure out how the Dems. and Reps. differ.
Liberals are
generally more emotional. This is why most artists/musicians are libs. Conservatives are
generally more practical and responsible with fortitude to get shit done. Don't say shit though, she's 12.
Govt. employees generally swing liberal. It's ironic, because in our state for example, the Republicans have offered more and it's really not close. A lot of that has been timing, but it is what it is. Unless under the influence of a heavy union, then blue collar workers swing conservative. This is consistent with practical thinking.
Those in our largest cities swing liberal, primarily because of diversity, propaganda and social "stir". Most of these people don't solve basic problems, because they're spoiled by social infrastructure. Those in rural areas etc. are far more likely to solve problems, and now we're back to practical again.
Conservatives hold things closer to the chest while liberals do the opposite (see emotional). Of course that's not always the case, look at Trump's mouth. A conservative is more likely to be honest or say nothing at all. A liberal is more likely to observe your words to gauge if you're consistent with their "hipster" narrative. They're less likely to not be completely honest, sometimes to pay a compliment or agree when neither are the case.
Conservatives are generally more independent, while liberals more dependent. This is consistent with the left's desire for more socialism, combined with the point larger cities swing liberal due to social infrastructure.
That's pretty well it, my opinion.
