Competitive Index Guide:

Most competitive races: Watch for contests that could go either way, including incumbents who'll face tough races and/or challengers with real expectations of winning.

Very competitive: Will likely be hard-fought, probably close races, but one side may start off with a political or electoral edge.

Potentially competitive: One side has a early edge because of the electorate or an especially strong candidate or incumbent, but there's room for things to get hotter if campaign dynamics change...

Probable Dem/GOP: Less likely to see heated contests this year, given partisan electorates and/or a strong candidate or incumbent on one side... but things can always change.
