House Speaker Paul Ryan joined Congressman Jeff Denham at a Modesto press conference Thursday in a bid to support his fellow Republican against a concentrated Democratic Party ad blitz to convince Northern San Joaquin Valley voters that he’s a Donald Trump clone.Denham waived off a question about the negative television campaign being waged against him. The query was about a commercial that specifically shows him pictured with Trump. Denham said he is more concerned about the needs of the Central Valley and the importance of bringing in water for the agricultural needs of farmers and residents of the many communities that have been suffering from years of drought.
