Sen. Patty Murray’s new budget plan will raise tax revenues by nearly $1 trillion while cutting spending by the same amount over the next decade, according to people familiar with the proposal…

Democrats expect to remain largely united, and Murray anticipates having the support of the 11 other Democrats on her committee, giving her enough support to send the bill to the floor on a party-line basis.

But the tax figure could present a problem for a handful of red-state Democrats up for reelection who Republicans will undoubtedly say are supporting a $1 trillion tax hike if they back the plan.
