Rhode Island's Democratic House speaker is outspending his Republican challenger 6-to-1 in a heated race for a General Assembly seat.

Campaign finance forms filed by House Speaker Nicholas Mattiello show he has spent about $187,000 since the election season began in July as he fights to keep his legislative seat representing western Cranston.

Republican candidate Steven Frias has spent far less during the same period, about $28,000.

The last campaign finance reports due before Tuesday's election were filed this week. Mattiello's forms show he has spent about $76,000 in the second half of October but still has nearly $230,000 in his account.

Mattiello also has a political action committee that has spent about $72,000 since the summer on political consultants and helping other Democrats running for office.
