Republican Tom Foley has loaned his campaign for governor another $1 million, raising his personal stake in the race to $4 million.
He now has raised nearly $4.9 million and spent nearly $4.6 million.
Foley recently promised he will not be outspent by Democrat Dan Malloy, who has received $6 million in public financing for the general-election campaign and $2.5 million for the primary.
Malloy has raised $8.7 million and spent $3 million.
Ned Lamont spent $9.5 million, including $9 million of his own money, in his losing bid for the Democratic nomination.
