It's голосами (typo)
ЕР - Единая Россия (a fraction/party whose representatives are in the "duma")
Read that abbreviation just like the letters read in the abc: йе, эр
yes, приняла = approved, accepted
проведёт -- yes, they hold it

"голосами" here means "via", "by means of" the votes of this fraction. (Not really standard usage)
