Yes there is widespread voter fraud, as in geographically widespread. Almost every large city has some voter fraud and usually in favor of democrats. However, it has been investigated intensely by Republicans, yet these no credible evidence of large scale voter fraud such as would alter the outcome of anything but a razor thin election. It's just Trump's excuse if he loses bigly to Hillary.
The majority of Democratic voter "fraud" cannot be easily exposed. Democratic operatives vote for other people. Nursing home and hospice patients have a better voting record than the general public. They write in votes for anybody they can get identifiers for. They bus derelicts to the polls for a free ride and a sandwich afterward. Most of it is not as illegal, as it is depraved.
