Yeah, with 2010, the US electoral map will become even more polarized:
California will probably be entirely Dem,
Southern or Western Democrats will be defeated, like Lincoln or in TN or WY,
NE Republicans will lose,
etc.
So, gubernatorial and senatorial maps will be increasingly in line with the presidential map, for the first time since... ? a long time anyway.
Is it a sign of bigger polarization ?
Polarization of political apparatuses or of voters ?
Or a sign of a more "nationalized" public opinion, because of media influence ?
How can you explain this strong trend ?
And don't you think it's boring.... ?
(apart from the fact that many Dems will be happy a "traitor" like Lincoln is defeated)
No.
