I doubt that he would blatantly and purposfully lie.
Buz,
How about something more along these lines, "Hovind uses selective recall and attention to delude himself about what the facts are in order to preserve for himself his version of the truth based on his understanding of Genesis and refuses to look at data which contradicts his prior convictions and superficial seizing on selected facts."? Though I actually think that Hovind is insincere and manipulative.
There are Billy Sundays and other frauds who make a nice living pretending to be God fearing. It isn't hard to do, believers can be be very gulible sending money in for prayer clothes and such. There are some of these guys on television that come across slimier than any used car salesman. Every false intonation and earnest look and pleading tone just screams "Con Artist" to me, yet millions? thousands ? of faithful take them to be sincere God fearing preachers.
I'll tell you nothing about Hovind seems sincere to me. His whole tone is too hyped, he is too slick and slippery. He sounds like a con artist, he talks like a con artist, and his doing it in the name of God has a long tradition in confidence trickery. If it walks like a duck and quacks like a duck I'm pretty darned confident it's a duck.
If Hovind isn't a duck he is doing a convincing imitation of one, uh, I mean con artist.
