By Jennifer Agiesta, Ariel Edwards-Levy, CNN(CNN) — Less than 100 days before the midterms, voters are agitating for wholesale change in Congress and looking to the Democratic Party in hopes of making that happen. Democrats lead Republicans on the generic ballot by 8 points among registered voters, according to a new CNN poll conducted by SSRS. Most Democrats want to see change within their partyDemocrats and Democratic-leaning independents are particularly eager for change within the party itself. Nearly 6 in 10 Democratic-aligned adults say their party needs at least major changes, if not complete reform. Seven out of 10 Democratic-aligned voters say their vote in November will be to send a message of opposition to the president, while just 41% of GOP-aligned voters say theirs will be a show of support.
