She has been shown to crush many Republican candidates in 2016, and the 2016 Republican field is crap, though if she doesn't run, then it's wide open.
I've seen the polling, and I don't understand why people love her. Could you please help me out?
Because a lot of people want a woman President (Me included), and she has managed to avoid any Gaffes that could destroy her reputation, and she's fairly within the mainstream.
Obama was the first African-American president, but how did his 1st term turn out so far? A first of anything DOESN'T guarantee it will be a success. If Hillary ends up being the first woman president, we'll see how she turns out.
