LOS ANGELES (CBS) — A newly-redrawn map of state Senate districts could have a noticeable impact on your checkbook.

KNX 1070′s Charles Feldman reports on the fallout of a California Supreme Court ruling.

The court ruling upheld new state senate maps drawn up by an independent redistricting commission that Republicans fear could give Democrats an edge in the elections in November.

If Democrats can gain more seats this November to the state Senate, they would likely be able to pass new tax legislation without requiring support from Republicans.

As man as 20 state Senate seats are up for grabs in the upcoming election.

GOP officials hope to get a referendum on the ballot to overturn the new districts, but that will be too late now for this year’s vote.

“What the justices are thinking really is, ‘Why should we get ourselves in this political question if it may never come to pass?’” said Larry Gersten, a political science professor at San Jose State University.

Republicans are expected to have enough valid signatures to get on the November ballot.
