Need political crossword help for homework

[fencesitter]

Helping my 14yr old with her gov't crossword got all but three.

1. 8 letter word for "these people formally elect the president" (no, it's not SCOTUS) --e--or- . Electorate doesn't work ??

2. 9 letter word for " this kind of 'bill' is unconstitutional" --t------.

3. 2 words for " paragraph 18 of the powers of congress" -l-s-i-----se.

This is tough.
