If you had any doubts, never fear -- War Room will be sticking with you tonight as results roll in from the four states (Ohio, Rhode Island, Texas and Vermont) holding nominating contests today. Here's our short rundown of the logistics.

Ohio: Primary. Polls close at 7:30 p.m. EST. 141 Democratic delegates and 85 Republican delegates are up for grabs.

Rhode Island: Primary. Polls close at 9 p.m. EST. 21 Democratic delegates, 17 Republican delegates.

Texas: OK, this one is where it gets complicated, for a couple of reasons. First of all, part of the state is in the Central time zone, while another part is in the Mountain time zone, so voting locations have different closing times. As a general rule, polls close at 7 p.m. local time, whatever the local time is; that means for much of the state, primary voting will end at 8 p.m. EST, while for the Western part of the state voting will end at 9 p.m. EST.

After the primaries, there's another wrinkle -- caucuses. These are supposed to begin 15 minutes after poll closing, but state election code specifies that "notwithstanding the hour set for convening, the convention may not convene until the last voter has voted at the precinct polling place." So if a given precinct has voting troubles during the primary, the caucus there could be delayed.

193 Democratic delegates, 137 Republican delegates.

Vermont: Primary. Polls close at 7 p.m. EST. 15 Democratic delegates, 17 Republican delegates.
